EDUCATION IN A SWISS CANTON. 293 



criticism of these arrangements on my part was met with a 

 counter objection to our system, which, in any particular 

 school, has the same length of day for pupils of all ages ex- 

 cept the very youngest. In Basel the weekly period for a 

 class varies from 20 to 32 hours. Even in the Primary Schools 

 alone there is a difference of six hours between the weekly 

 period of the lowest class and that of the highest. The Rector 

 of the Upper Realschule, however, is firmly convinced that 

 forty-minute periods are to be preferred and. along with many 

 of the other teachers, is pressing" for their introduction into 

 the schools.
